MPF42791 Datasheet | Monolithic Power Systems

2 to 16 Stacked Cells Battery Pack Fuel Gauge with Resistance Detection and Thermal Model DESCRIPTION The MPF42791 is a drop-in solution to provide prehensive status information on lithium-ion battery strings up to 16 series cells. The MPF42791 estimates the internal state-ofcharge (SOC) and state-of-health (SOH) for each cell, as well as the full pack. The MPF42791 also determines impedance, remaining runtime, charge time, and instantaneous available power. On-board memory enables the lifetime logging of key parameters. The MPF42791 is simple to use and supports a variety of lithium cell chemistries and cell sizes. A few basic configurations allow for quick set-up, and...
